and used on the terminal.
Start-Up
• Check the wiring for proper connections.
• Consult the Flowrite 599 Series SKB/C/D 62UA
Series Electronic Valve Actuator 24 Vac
Proportional Control Advanced
FeaturesTechnical Instructions 155-717 for
detailed commissioning instructions.
Stroke Calibration
To determine the stroke positions 0 and 100% in the
valve, calibration is required when the valve/actuator are
commissioned for the first time.
The actuator must be mechanically connected to a valve
and must have a supply voltage of 24 Vac. The
calibration procedure can be repeated as often as
necessary.
To initiate the calibration procedure, short
circuit the contacts inside the slot located
on the printed circuit board (with a
screwdriver).
Automatic calibration proceeds as follows:
• Actuator runs to the 0 stroke position (1) the green
LED flashes .
• Actuator then runs to the 100% stroke position (2)
the green LED flashes.
• Measured values are stored in the EPROM.
• The actuator now moves to the position defined by
control signal Y or Z (3), and the green LED now
glows steady (normal operation)
• Throughout this procedure, output U is inactive,
meaning the values only represent actual positions
when the green LED stops flashing and remains
on continually.

CAUTION:
Before starting calibration, be sure that the
manual adjuster is set to Automatic to
register the actuator values.
